We do have a local controller option with our Control hardware appliance, if you want to be able to configure locally.
I’d like to double check what you are saying though. You have Internet access while you are setting up Route10 (i.e. via 192.168.1.1 or mobile app), but then you lose connectivity after you set it up on VLAN911? If that is true, can you set it up using the standard VLAN1 first, and then invite me to understand why VLAN911 isn’t allowing access?
